白屏没有错误提示一般是php.ini的display_errors没有启用的问题

所以首先确保display_errors已经是On的状态

然后打开Debug模式

在app/config/app.php中将’debug’=>false 改为’debug’=>true

这样如果是PHP或者配置问题就会在页面中显示

如果是框架或者程序问题,就可以在app/storage/logs/laravel.log中找到具体错误.

几个常见的无法启动laravel问题

1.没有配置转发规则

Apache在.htaccess中设置

Options +FollowSymLinks
RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]

Nginx在配置文件中添加
Copy after login
location / {
    try_files $uri $uri/ /index.php?$query_string;
}

2.app/storage的写入权限
chmod -R 777 app/storage 给了权限就可以

3.open_basedir的设置问题
因为一些自动工具会自动的将open_basedir设置到域名所在的跟目录,也就是public目录,但其实open_basedir应该在public上一级目录
在站点配置或者php.ini 或者 httpd.conf中改过来重启下对应的服务即可

最后还可以在根目录使用php artisan env来查找错误
Copy after login
